METHOD FOR CONTROLLING A PRESSURE GRADIENT OF A POWER BRAKE SYSTEM
A method for controlling a maximum permissible pressure gradient of a power brake system of a motor vehicle. The method includes continuously calculating a maximum permissible pressure gradient, starting from a current motor speed gradient and motor speed of an external-force brake pressure generator, taking into account a predefined maximum permissible motor speed and a predefined maximum permissible motor speed gradient. In a next step, the maximum permissible pressure gradient is continuously transmitted to brake pressure demand units, so that, in the case of a braking event, the pressure gradient requested by the brake pressure demand units or resulting from a requested pressure is generally less than or equal to the maximum permissible pressure gradient.

Controller and control method
The present invention obtains a controller and a control method capable of hastening identification of an object or an event to be focused by a rider of a straddle-type vehicle, the rider having perceived haptic motion. A controller (51) for a rider-assistance system (50) mounted to a straddle-type vehicle (100) includes: a determination section that determines necessity of a warning given to the rider; and a haptic motion performing section that performs haptic motion at least once to reduce or increase acceleration/deceleration of the straddle-type vehicle (100) only for a moment. The haptic motion performing section changes a priority of each wheel (3, 4) at the time of changing a braking force to reduce or increase the acceleration/deceleration only for the moment in the haptic motion according to a focusing direction that is a direction in which the rider should focus by the warning.
Brake control device for vehicle
A brake control device is applied to a brake device that controls a front-wheel braking force and a rear-wheel braking force. The brake control device includes a ratio calculation circuit that calculates a target front and rear braking force distribution ratio based on a target pitch angle, and a brake control circuit that performs a stability control by operating the brake device based on the target front and rear braking force distribution ratio during braking.
Controller and control method
The present invention obtains a controller and a control method capable of appropriately executing adaptive cruise control for a straddle-type vehicle while securing a driver's comfort. In the controller and the control method according to the present invention, when braking forces are generated on wheels of the straddle-type vehicle during adaptive cruise control, in which the straddle-type vehicle is made to travel according to a distance from the straddle-type vehicle to a preceding vehicle, motion of the straddle-type vehicle, and the driver's instruction, at a braking start time point at which the braking force starts being generated on each of the wheels, braking force distribution between the front and rear wheels is brought into an initial state where the braking force generated on the rear wheel is larger than the braking force generated on the front wheel. Then, a distribution ratio for the front wheel in the braking force distribution between the front and rear wheels is increased with a lapse of time.
Braking control system for an aircraft
A braking control system for an aircraft having braking wheels, the braking control system being configured to receive input of signals from sensors representative of a plurality of measured aircraft parameters, and to output a plurality of brake commands to brakes associated with the braking wheels, wherein the braking control system includes a health monitoring system for determining the operability and/or reliability of the sensor signals and/or of the braking wheels, and a task manager for automatically self-reconfiguring the braking control system so as to change the manner in which the braking control system utilises the input signals in the event that the health monitoring system judges a failure of one or more of the braking wheels or sensor signals. Also a method for operating an aircraft having a plurality of braking wheels.
